Signaling a major shift in its model line-up, Pontiac Motor Division unveiled a revolutionary, new-generation Grand Prix in 1969.

The attainment of new goals in safety; a concealed radio antenna - a first in the industry; and Pontiac's precision engineering coupled with trend-setting styling establish the Grand Prix as America's most distinguished automobile.

Called the Model J, the GP takes on classic proportions with a one- of-a-kind body that rides on an exclusive 118-inch wheelbase. The Model J is available in one body style - a hardtop coupe. It was released September 26, 1968.

Among the Grand Prix's host of innovations in addition to the concealed radio antenna are an electrically heated rear window defogger, a driver's command seat completely enclosed in energy-absorbing material for optimum protection and the longest hood in the industry.

A special custom option, called the Grand Prix Model SJ was available. It consists of the 428 cubic-inch large valve V-8 engine, automatic level control, power disc front brakes, special instrument panel gauges, lamp group, Polyglas tires and special high-performance suspension.
